Nice selection of skis Liam..
I go back a long way with Head through the IM series including their 88...
The Rev 105 is truly a different ski..probably not for everyone. I did drop down to the 171 length giving my son my 181..he's 4 inches taller and 70 lbs heavier.
The Rev 105 turns, floats, and bumps amazingly well and even on western groomers...the freakn' thing rips...blew me away.
In all ...there are so so many fine skis out there....the trick is...the right fit!
It might be helpful for those looking for new skis to make a list of the features that are the highpoints of their ideal target ski.
here's one I was playing with just recently involving a pow ski:
